Increase of "Selište" dam weir capacity

Abstract

Increase of the storage capacity od Selište reservoir on the Zgrža stream on mountain Goč in the vicinity of the city of Vrnjačka Banja, has to be achieved by an increase of the dam’s existing structures. The labyrinth weir is a good choice due to a substantial increase in the weir crest length, while keeping the overflow head low. The use of the labyrinth weir additionally achieves the maximization in the storage capacity. This paper presents the existing state of dam, overtopping design concept, hydraulic calculation and proposed design.
